Neville insists other commitments will take priority in the short term and that he may not return to the dug-out ever again.

Speaking to Sky Sports, Neville said: "I always say 'never say never' because my love of football is too great, but I genuinely believe it will be very difficult for me to go back into coaching because of my commitment now to so many different things.

"It's my obligation to deliver Salford City to the Football League. It's my obligation to roll out Hotel Football internationally.

"It's my obligation to deliver high-end restaurants with Michael O'Hare. It's my obligation to deliver St Michael's, which I believe is the best development in Manchester.

Gary Neville given a grilling by Jamie Carragher on Monday Night Football from Valencia disaster

"I cannot open that hotel and blame the general manager for it failing. Why? I appointed the general manager.

"I can't go to Spain for four months, be coach of Valencia, and blame the fact there was a difficult dressing room, I didn't speak the language, we had bad luck and we missed some chances.

"Why? Because I knew I didn't speak the language before I went, I knew it was a difficult dressing room, I knew they had sacked lots of managers and I didn't deal with it.

"People will always look at that externally and think it was a negative experience. For me personally, I lost football matches but what I gained was general experience of life, culture and appreciation for a different country.

"I thought, 'When am I going to get offered an opportunity like this again?' An English manager coaching a top-four club in Spain.

"I knew I didn't speak the language and had been on courses where foreign coaches had talked about the challenges and problems when you don't speak the language.

"There were two or three big things I did wrong and should have been more insistent on, but I also knew the reason why the owner wanted me to take the job was because he didn't want a coach to come in, lump six players out, create more upheaval and bring six new coaches in."
